Abracket33 extends between the members 31 and 32 and the rear end of theshaft 14 connected to the power takeoff of the tractor I9 is rotatablymounted in the bracketlds and (a :sheave 40 is fixedly mounted thereonwhich carries a V-belt 41 which extends over a sheave 42 fixedly securedto a shaft 43, rotatably mounted in a bracket 44 secured'to the supportmember 21 and the shaft 43 which extends longitudinally of the hopper 16and is rotatably mounted in a bearing, not shown, secured to therearmost support member 21 and is provided with a bevel gear 45 securedto the rearmost end thereof. :Ihe bevel gear 45 meshes with a bevel gear46 fixedly mounted on one end 161* a transversely iextending shaft 41.having a bevel gear "48 .fixedl-y mounted on the other end .The shaft4:1 is u'otatably mounted in horizontal portions 52 and 53,respectively, of :an' auxiliary frame also having .a transverse portion54, the portions '52, 53 and :54 formthe auxiliary frame and being:suitably secured to each other and the foremost ends of the portions 52and 5.3 arezsecured to the lower ends of vertical members :55 .and 55secured in :spaced relation *to each other on the support members 2| and22.

4A 'pairaof brace'mds an and 6.1 have their lower ends suitablyzsecured.to the respective portions :52 and 53 :of the auxiliary frame, :as bywelding, the brace 'I'U'ds 26.9 and 6:1 extend upwardly rand iforwardlyand are :secured at their upper ends to support members D and 51, .as bywelding. iBrace sro'ds $5 and B6 :are secured at their lrear ends flzothezsupportzmembers 59 and 51, re- :spectively, and the brace rods '55and '36 extend forwardly and are suitably secured to vertical members 55and 155.

Bearings "I35 and 71.6 :are secured to the outer surfaces oftheiframemembers 52 and :53, respectively, as :by U-bolts I?! :and 18and the bearings :15zand 16 are disposed in thesame vertical .plane asthe :shaft 4] and have rotatably mounted therein vertically disposedshafts 89 and 81 hav- Zing ibevel gears 292 and 18:3 .meshing with thebevel .gears 46 and #8, respectively. Fixedlysecuredto the lower ends ofthe shafts =89and '81 are rotors or fans Q85 and 86., each .oftheIrotoI'S1B5 and .86

being identical and comprising a circular plate 38?! havingza pluralityof radially extending angle :irons $8 suitably secured thereto as bywelding. It is thus .seen that :rotation .is transmitted from the powertake-off 11 through the shaft 43 and gears 45, 46, '48, 82 and 8.3 :torotate the rotors 85 and $6 which are adapted to distribute materialsuch as fertilizer :and seeds deposited thereon to each :side of thebroadcaster.

The be'd plate 19 extends "longitudinally of the hopper 16 and sprocketwheel .99 is rotatably mounted on ashaft 90 fixed'in a bracket 91:secured "to the unembers 31 and '32 adjacent the 7? front-of the-bedplate :19 in Figure 1 and a simi- "lar sproket wheel 92 is mounted on ashaft 93 mounted in a manner to be described at the rear end of the bedplate 19 as may be observed in Figure 5, the sprocket wheels 89 "and 92being disposed below the bed :plate 19 and having an endless conveyor 94extending thereaboutso that 'thelower surface of the upper reach of theconveyor 94 will move along the top surface :of the bed plate 19.Secured to the conveyor 94 at spaced intervals are a plurality of pipes95 of substantially the same width as the bed plate 19 to cause rearwardmovement of material on the bed plate 19 as the endless conveyor 94 ismoved in a clockwise direction in Figure 5.

Means are provided for transmitting rotation to the sprocket wheels 89and 92 for moving the conveyor :94 comprising a :cam wheel 150i) fixedlysecured to the right-hand end of the shaft 4'1 (Figures 3 and 4) havingan arm 101 pivotally secured in off center relation thereto as by a bolt1112. The arm 191 extends forwardly from the shaft 4'! and has its frontend pivotally and adiiustably connected to a vertical bar 105 as by avbolt 10.6. The .bar 105 has its lower end rotatably mounted on theshaft 93 on which the sprocke't wheel 92 is mounted, the shaft 93extending transversely of the broadcaster and havmg a ratchet Wheel.1418 fixedly mounted thereon. The shaft 295 :is .rotatably mounted in:a bearing @119 secured to an arm, not shown, suita'blysecured to thevertical member =56 and the end of the shaft 9-3 remote from the ratchetwheel 498 is :mounted :in a ibearing bracket H l :secured *to avertically extending angle arm 1H2 secured adjacent the bed .plate 1-19of the :conveyor, there being a similar vertically extending angle arm21:1 .3 secured adjacent the other :side :of the :bed plate 19 forsupporting the same at rthe :rear hi the distributor.

The bar e195 has a :dog 211 5 rrotatably secured thereto as at 1 :16 and:a tension spring 11 I :isssecured to the :free end of the .dog .145 and*to the vertical bar 1495 :andnormally urges the dog 1-15'in-a'counter-iclock-wise direction in.Figure:-8. Re- .ferr-ing toFigure :8, :it will be observed that the :dog .115 engages the :teeth ofthe ratchet wheel 1'98 :and upon rotation of the shaft 4:1 K013813101).will be imparted to :the team Wheel 110.0 to cause the arm I 051 to move:to the Eleft in :Figure 8 'whereby the dog 1215 .in engagement "withthe 'teeth'on theratchet wheel 108 will-transmit steprby-step movement:to "the matchet wheel 1118 thus transmitting step-by-step movement tothe :sprocket Wheels 39 and 92 to move the endless conveyor =94 to causethe material disposed withthe hopper 115 to be moved to the rearthereof.

The :rear wall 220 of the hopper 165 :has an opening 1143 i110perinittmaterialsuch as fertilizer disposed within ithe hopper -15 to bedistributed from the rear end of the shopper :as the :conveyor '94 is:moved along the bed plate 1:9. The angle irons 1:12 and :lrL3 aresecured to :the rear wall :20

:of the hopper :16 at the opposed edges aof the opening and serve asguides :for .a gate .1 9! having :a plurality of transverse bars E1218suitably secured thereto :and the angle :irons i112 and 5113 each have.a vertically extending 'slot 1.11.9 therein which isslidablytpenetrated "by the :ends of the transverse Tbars 11:118.

A lever 1.21] has one :end ipivotally secured to the upper :end 10f thegate and extends outwardly through the slot I19 in the angle iron 5113and is 'adjustably zpositio'ned ron acne of the rearmost frame members22 by means of a .pin 11:21 and a. plurality "of bores 1:22 the :framemember .22. The .lever permits adjustment of the gate 211121 "toregulate the size ;0f the opening 119 and to lcontrol "the amount :ofmaterial that is discharged .from the :hopper .16.

A .chute in the form ad :a :plate 122:5 is disposed beneath the rear end:of the iconveyor '94 and extends faetween frame members 52 and 53 thevertical as may be observed in Figure 5 and its upper front end isdisposed directly beneath the discharged end of the conveyor 94 and itslower rear end is disposed above the rotors 85 and 86 but in spacedrelation thereto. It is thus seen that when material is discharged fromthe discharge end of the conveyor 94 onto the chute I25 it will slidedown the chute I25 onto the rotors 8'5 and 86 and as the rotors 85 and86 are rotated, the material will be distributed from the rotors to eachside of the broadcaster.

Suitably secured to the centermost portion of the chute I25, as bywelding, is a material diverting plate member I 26 bent at right anglesand having its apex disposed in line with the center of the bed plate I9to thus cause the material being discharged from the conveyor 94 ontothe chute I 25 to be diverted on each side of the member I26 onto therotors 85 and '86.

If it is desired to have the material from the hopper I6 fall onto onlyone of the rotors 85 and 86 a hinged plate member may be provided havingportions I30 and I3I so that the portion I30 may be secured to thematerial diverting member I26 as by a removable spring clamp I33 and theportion I3I may be moved in alinement with the portion I30 and with thehinge point disposed below the apex of the member I26 so that the freeend of the portion I30 will be disposed adjacent the right-hand edge ofthe bed plate I9 in Figure 4 so that material discharged from theconveyor 94 will be caused to slide along the hinged portions I30 andI3I to fall only on the rotor 85 and not on the rotor 86. If desired,the hinged member may be secured to the other side of the materialdiverting member I26 to direct material from the conveyor 94 to therotor 86 instead of the rotor 85. When it is desired to use both rotorsthe hinged member may be disposed with its hinge point at the apex ofthe member I26 and with the portions I30 and I3I disposed in parallelrelation to the walls of the member I26 and flush therewith.

Oscillatably secured to the lower surface of the chute I25 as by boltsI40 and MI are segmental has heretofore been possible in that by usingthese novel means material may be distributed to one or both sides ofthe broadcaster as desired and the angle at which the material isdistributed may be changed as desired.

As has heretofore been stated, the hopper I6 may contain any suitablematerial and is pref- "erably used for fertilizer and the like to permitthe fertilizer to be discharged from the rear end of the hopper by theconveyor 94 onto the chute I25 and onto the rotors 85 and 86 to bebroadcast to one or both sides of the broadcaster.

Now, it is frequently desirable to distribute and broadcast othermaterial at the same time the fertilizer is broadcast, and to this end,there is provided a second hopper broadly designated at I which may beused for storing any suitable material such as seeds'and the like andwhich is preferably formed with a front wall I62,

a rear wall I63 and side walls I and I66, forming a hopper in the shapeof an inverted truncated triangle. The bottom of the hopper I60 isdisposed substantially midway of the vertical height of the broadcaster.The hopper I60 is secured to the rear-wall 20 of the hopper I6 in anysuitable manner as by bolts I61 and I68 penetrating spacer members I10and HI, the spacer members I10 and HI extending transversely of thebroadcaster and holding the hopper I60 in spaced relation to the rearwall 20 of the hopper being rotatably mounted on the side walls oftheplate members I42 and I43. The segmental plate members I42 and I43 maybe manually moved to any desired position to extend the surface of thechute I25 rearwardly over the rotors 85 or 86 as desired.

When the segmental plate members I42 and I43 are disposed completelyunderneath the chute I25 so that no portion thereof extends beyond therearmost end of the chute I 25, material fall-' ing from the chute I25onto the rotors 85 and 86 will hit the rotors 85 and 86 at a pointsubstantially directly beneath the rearmost end of the chute I25 andwill be distributed from the rotors, in a line tangent thereto extendingfrom this point. Now by moving the segmental plate members I42 and I43outwardly about the pivot points I40 and MI the material from the chuteI25 will strike the rotors 85 and 86 at a different place and will thusbe distributed in a line tangent to this point on the rotors. It is thusseen that by use of the novel segmental plates I42 and I43 the materialfalling from the chute may be directed to a desired point on the rotors85 and 86 to thus vary the angle at which the material is broadcast fromthe rotors.

By use of the novel segmental plate members I 42 and I 43 and the novelmaterial diverting members I26 with the hinged plates I30 and I3Imaterial may be distributedmore efiiciently than the bottom plate I 15so that material such as seeds falling through the opening I11 in thebottom plate I15 will strike against the toothed wheel I83 which whenrotating will break up the seeds and separate them and move them to thebottom portion of the housing I which is provided with an opening I86 topermit the material such as seeds to be discharged therefrom onto thechute I 25 at substantially the same point at which material from theconveyor 94 is discharged onto the chute I25 so that the material fromthe hopper I60 will be distributed in a like manner to the material fromthe hopper I6. The toothed wheel I83 acts as agitating means tofacilitate the discharge of material from the hopper I60.

In order to regulate the amount of seeds or other material falling fromthe hopper I60 through the opening I11 in the bottom plate I15, there isprovided a closure plate I81 mounted for transverse sliding movementagainst the lower surface of the bottom plate I15 and penetrating thewall of the housing I80. The closure plate I81 has a handle I88 suitablysecured thereto and extending rearwardly at a right angle therefrom,said handle I88 being mounted for transverse sliding movement in abracket I90, the bracket I90 being provided with a plurality of spacedbores, not shown, so that a bolt I92 penetrating the handle I88 may bedisposed in one of said bores for positioning the handle I88 at thedeclaims.

' :Iplaim':

77 sired position thus positioning theslidingclosure plate --l-8'| inthe desired position to restrict the size of the opening 4-11 in thebottom plate H5 as desired or to close the same.

The shaft I85 extends to .theleft in Figure'3 sand is rotatably mountedin a bracket l95 -suitably secured .to a vertically disposed channelmember I96 suitablysecured to the spacer members ill and 1-14 on the'rear wall of the hopper [6. 7

A sprocket wheel =-Zllll isfixedly mounted-on the shaft I85 between arms-of the bracket I95 and has a sprocket chain .201 extending therearoundand also extending over a sprocket Wheel 1112 .fi-xedly mounted on .theshaft 41 which has the beveled gears 46 and 48 mounted thereon and :is

, driven through the shaft 43 by the power takeoff of the tractor. ;Itwill thus be observed that as the shaft 41 is caused to rotate in amanner heretofore described, thesprocketwheel 202 will rotate in a likedirection transmitting rotation ,to the sprocketwheel 2 0 0 and theshaft 185 which will cause the toothed wheel i83 disposed within thehousing 1.80 to rotate to thus segregate :and

assist in distributing material such as seeds from the hopper I 60.

A suitable-manually operable clutch 203 is provided associated with thesprocket wheel 202 to .permit the shaft 41 to rotate without rotatingthesprocket wheel 202 when desired.

It is thus seen that there is provided an improved broadcasterhaving ahopper. adapted to contain .material such .as fertilizer, said shopperhaving a bed plate extending longitudinally thereof and being providedwith an endless conveyoron said bedplate and said conveyor having meanssecured thereto for moving materials from the .front of said hopper tothe rear thereof and for discharging .the same onto a chute, and meansbeing provided on'the chute for diverting the material dischargedthereon on to one or two 'rotors secured to the rear of the broadcasterand driven by connecting means connected to the power take-off of thetractor, .andsaid connecting means also "being connected with 'a camwheel for actuating means for causing rotation'ofthe 'conveyor instep-by-stepmovement to periodically 'discharge material from the hopperonto the rotors.

It is also seen that there is provided asecond hopper adapted to containmaterial such as "seed and means are provided for transmitting rotation"from the power take-off through the'conneoting means for rotating therotors andac'tua ting the conveyor to rotate a toothed wheel disposed*beneath the second hopper to cause material therein to be distributedtherefrom and the second hopper also being provided with means toreg'ulate the 'flow of materials therefrom.

By the use of this improved broadcaster, both fertilizer and seeds :maybe distributed from a single distributor or broadcaster and the amountthereof may be regulated as well 'as the :angle at :which the :seeds andfertilizerarerdistributedaand, desired, they :may be distributed fromoneside "of the device or from both sides at any desired :angle.
